Kiai Hajji Ali Yafie (September 1, 1926 -) is a faqih and former chairman of the Indonesian Ulema Council. He was a prominent figure of Nahdlatul Ulama (NU), the largest Islamic organization in the world based in Indonesia, and had served as a temporary chief adviser from 1991 to 1992. Currently, he is still active as a principal of Pondok Pesantren Darul Dakwah Al Irsyad in Parepare, South Sulawesi, which he founded in 1947, and as a member of the advisory board for the Indonesian Association of Muslim Intellectuals (ICMI).
Ali Yafie received his first education at a public elementary school, and continued the higher education at As'adiyah Madrasah in Sengkang, South Sulawesi. His major was Usul al-fiqh and he is widely known in Indonesia as an expert in this field. He devoted himself as a jurist in the religious courts of Ujung Pandang from 1959 to 1962, then an inspectorate of the East Indonesian Religious Court from 1962 to 1965.
From 1965 to 1971, he became the dean of the faculty in the Ushuluddin State Institutes of Islamic Studies based in Ujung Pandang, and was active in NU at the provincial level. He became active in NU nationally from 1971. At the 1971 NU conference in Surabaya he was elected as an executive, and he was appointed to the House of Representatives after the election. Then he remained as a member of the House until 1987, when Djaelani Naro no longer put him in the list of candidates.
Since then, Ali Yafie taught at various Islamic higher educational institutions in Jakarta, and became increasingly active in MUI. At the same time, he was re-elected as an executive at the 1979 NU conference in Semarang and 1984 conference in Situbondo, and in the 1989 conference in Krapyak as the representative of the chairman. Because Ahmad Siddiq, the incumbent chairman of the advisory board, died in 1991, he acted as the deputy chairman of the advisory board temporarily until 1992. After having disputes with Abdurrahman Wahid regarding the issues of aid from the Foundation for Social Welfare Fund, Ali Yafie withdrew from NU.
